It mounts on DIN rail in any orientation and accepts supply from top or bottom. The 10 kA breaking capacity per EN 60898 covers residential and commercial branch circuits; the 20 kA rating per IEC 60947-2 means it can also handle industrial fault levels where the prospective short-circuit current is higher. The C-curve (5–10× In) is the standard choice for mixed resistive and moderate inductive loads — lighting, small motors, general socket outlets — where nuisance tripping from inrush is unlikely. ## Key ratings — what they mean for the panel Rated operational voltage is 110/120 V AC, 50/60 Hz. The insulation voltage (Ui) is 264 V, and overvoltage category III with pollution degree 2 means it's rated for fixed installation downstream of the main distribution board — not for outdoor or wet locations. Surge voltage resistance is 4 kV, adequate for standard transient protection in residential and light commercial panels. The 30 mA type A residual-current element detects pulsating DC fault currents (typical from rectified loads like electronics or LED drivers) as well as sinusoidal AC faults. Mechanical service life is 10 000 operating cycles, which is typical for a panel-protection device — not a switching contactor. ## Mounting and integration The 5SU1324-7KX10 occupies 3 modular width units (54 mm) on a DIN rail. Installation depth is 70 mm; overall depth with terminals is 77 mm. IP20 rating applies only when installed in a distribution board with connected conductors — the device itself is not sealed against dust ingress. Halogen-free and silicon-free construction matters for panels in environments with sensitive electronics or where low-smoke, zero-halogen cabling is specified. Ambient temperature range is -40 °C to 75 °C, which covers most indoor panel environments including unheated enclosures.","metaTitle":"Siemens SENTRON 5SU1324-7KX10 RCBO, 2P, 10 A, C-curve, 30 mA","metaDescription":"Siemens SENTRON 5SU1324-7KX10 RCBO, 2-pole, 10 A, C-curve, 30 mA residual, 10 kA (EN 60898) / 20 kA (IEC 60947-2), 110/120 V AC, halogen-free.

However, the 5SL4363-7 is a 3-pole MCB; the 5SU1324-7KX10 is a 2-pole RCBO. The wiring differs — the RCBO requires both phase and neutral connections plus the residual-current sense loop. No rewiring of the busbar is needed if the panel already has a 2-pole arrangement, but the neutral must be routed through the device."},{"question":"What compliance documentation is available for 5SU1324-7KX10?","answer":"The 5SU1324-7KX10 carries IEC 60898 and IEC 60947-2 ratings, indicating compliance with the respective standards for MCB and RCBO performance.
